c++ exceptions and program execution logic
- by Andrew
Hello everyone,
I have been thru a few questions but did not find an answer.
I wonder how should the exception handling be implemented in a C++ software so it is centralized and it is tracking the software progress?
For example, I want to process exceptions at four stages of the program and know that exception happened at that specific stage:
1. Initialization
2. Script processing
3. Computation
4. Wrap-up.
At this point, I tried this:
int main (...)
{
...
// start logging system
try {
...
}
catch (exception &e)
{
cerr << "Error: " << e.what() << endl;
cerr << "Could not start the logging system. Application terminated!\n";
return -1;
}
catch(...)
{
cerr << "Unknown error occured.\n";
cerr << "Could not start the logging system. Application terminated!\n";
return -2;
}
// open script file and acquire data
try {
...
}
catch (exception &e)
{
cerr << "Error: " << e.what() << endl;
cerr << "Could not acquire input parameters. Application terminated!\n";
return -1;
}
catch(...)
{
cerr << "Unknown error occured.\n";
cerr << "Could not acquire input parameters. Application terminated!\n";
return -2;
}
// computation
try {
...
}
...
This is definitely not centralized and seems stupid.
Or maybe it is not a good concept at all?
